Via Nanfang Ribao, a long report: Guangdong H7N9 virus mutates outbreak occurred is still dominated local dissemination. The Google translation of the report is often as baffling as the headline, but it does have one important passage:
From 15 new cases notified since Dongguan, Guangdong and has five days in a row in the four cases of H7N9 informed critical cases, does this mean that expanding the scope of the epidemic?
In this regard, Zhang Yonghui response, since August since the first case was found, Guangdong Province on six cases of human infection with the H7N9 avian influenza cases 441 close contacts of a strict medical observation and pathogen detection, were not unusual. In addition, the provincial CDC also isolated from the province and in some cases environmental H7N9 avian influenza virus genome sequencing, discovered in east China with cases of avian influenza virus H7N9 infection in highly homologous, which means the virus to "Tamiflu" drug-sensitive, drug-resistant mutation has not yet occurred.
"Based on this, the province this winter and spring of human infection with H7N9 avian flu epidemic will continue to localized mainly sporadic cases and severe cases have occurred, but the recent local outbreak or epidemic outbreak risk is very low, which means that the epidemic appears diffusion or low likelihood of spread. "Zhang Yonghui said.
□ illness Two cases of low and stable, two cases of worsening
At present the province's six cases of human infection with the H7N9 cases, two cases have been cured, the remaining four cases of the disease in patients with concern.
Chinese Academy of Engineering, the clinical team leader province prevention of human infection with H7N9 avian influenza Zhong Nanshan said: "These four cases in two cases stable at a low level, and another two cases there are signs of deterioration, one case in Shenzhen, one case Yangjiang's. "
In the diagnosis, Zhong Nanshan, emphasized that this experience from several cases in Guangdong, the light detecting upper respiratory swab is not enough, "diagnostic swabs positive rate is relatively low, so the lower respiratory tract screening must be confirmed."
In terms of treatment, Zhong Nanshan considered to be a continuation of past practice, once the flu-like symptoms, it is necessary to use as early as neuraminidase inhibitors such as Tamiflu, "thought the virus in 10-14 days will be gone, but the Dongguan Patients in turn is the first 15 days, the virus is still strongly positive, and we observed decreased dynamically make use of Tamiflu viral load, indicating that it is effective, so if two weeks after the patient as well as viral infections is to insist on medication."
Zhong Nanshan also highlighted the comprehensive treatment, the importance of a comprehensive treatment, "We found that patients with cardiac function, hematopoietic function, liver damage, etc. So simply relying on anti-infection treatment is not enough, you need a comprehensive treatment, the mortality rate dropped to minimum.
